NOVATO (CBS/AP) — Highway workers have unearthed artifacts used by a Native American tribe as part of a paving project along Highway 101 north of Novato.

Arrowheads, parts of grinding bowls, stone tools and shells used by the Coast Miwok were discovered during the project, which archaeologists say has uncovered an area used by native people over several hundred years.

A crew of up to 25 archaeologists including a team from California State University, Sacramento is now digging and sifting through the soil to bring the artifacts into light.

Members of the Federated Indians of Graton Rancheria Sacred Sites Committee, who are of Coast Miwok descent, are monitoring the dig.
